Fragrant white flowers are produced on pendulous panicles from November through April on nodding clerodendrum (Clerodendrum nutans), a large, non-hardy shrub native to the Himalayan mountains. Grow this plant in a sunny, frost-free location, and keep the soil moist throughout the year.

The genus name of this plant is derived from the Greek kleros (chance or fate) and dendron (tree), thought to be a reference to its inconsistent results when used as a medical remedy by early Greek culture.
